Om (ॐ): The Complete Meaning of the Most Sacred Symbol in Hinduism
Om is the primordial sound and the most recognised symbol of Hindu, Buddhist and Jain traditions. Understanding its three parts, the silence after, and how it is used in meditation.
Om. Three letters that carry more meaning than many philosophies combined. The Mandukya Upanishad opens with the startling sentence: "Om iti etat aksharam idam sarvam" — "Om, this one syllable, is all this." Not just a holy sound, but the universe itself compressed into a vibration we can speak.
Three letters, four states of consciousness
Om is actually A-U-M + silence. The Mandukya Upanishad maps it to four states:
- ✦A — the waking state (jāgrat), the world of the senses
- ✦U — the dreaming state (svapna), the world of the mind
- ✦M — the deep-sleep state (sushupti), pure undifferentiated awareness
- ✦The silence after — turīya, the fourth, the witness that holds all three
Chanting Om therefore takes the mind on a micro-journey from activity to dreams to stillness to the silence beyond — in about six seconds.
Why Om is called the Pranava
"Pra-nava" means that which is ever-new. The sound of Om is said to be the very vibration of creation — the first movement of consciousness as it becomes the universe. When you chant it, you are joining that primordial vibration. The Yoga Sutras of Patanjali say simply "tasya vāchakah pranavah" — the name of the supreme is Om. Meditation on Om, the Sutras go on, removes obstacles and grants self-knowledge.
The shape of the symbol ॐ
- ✦The large lower curve — waking state
- ✦The upper curve — deep sleep state
- ✦The middle curve coming out — dream state
- ✦The dot (bindu) — turiya, pure consciousness
- ✦The half-moon under the bindu — māyā, the veil that must be pierced to reach it
How to use Om in daily practice
- ✦At the start of every mantra or mantra-session — it connects your individual voice to cosmic sound.
- ✦Three long Oms before pranayama or meditation — they settle breathing.
- ✦After exercise, stress or before sleep — Om chanted aloud for one minute changes the nervous system palpably.
- ✦As a mental anchor during anxious moments — silent Om on each in-breath and out-breath.
A simple evening practice
Sit comfortably at sunset. Take three natural breaths. Inhale, and on the exhale chant Om slowly — about four seconds for A, two for U, three for M, and hold silence for three. Do 11 such Oms. On the 12th, stay silent and simply listen. Most people report — within a week — that they start hearing an inner hum. That is not imagination; it is the nādā, the unstruck sound, always present behind thought, which Om simply makes audible.
